{975} How to check, SMPS PWM IC switching or not?

in this video number {975} How to check, SMPS PWM IC switching or not? i demonstrated how we can test/ check / verify any PWM controller IC (pulse width modulation controller ic) in smps switch mode power supply using multimeter. i discussed (UC1842 / UC2842 / UC3842 / UC1843, / UC2843 / UC3843 / UC1844 / UC2844 / UC3844 / UC1845 / UC2844 / UC3844 / KA1842 / KA2842 / KA3842 / KA1843, / KA2843 / KA3843 / KA1844 / KA2844 / KA3844 / KA1845 / KA2844 / KA3844. when vcc voltage are applied to its vcc pin number 7 and return to pin 5. it produces 5 volt reference voltage from pin number 8. pin 4 is RT / CT. pin 4 also can be configured with any external clock signal. it have 2 shutdown techniques.
